NMR Spectra. Hydrogens attached to carbon adjacent to the sp 2 hybridized carbon in aldehydes and ketones usually show up 2.0-2.5 ppm.. Aldehyde hydrogens are highly deshielded and appear far downfield as 9-10 ppm. Chemical shift of each protons is predicted by 1 H chemical shift ranges (H a): chemical shift of methyl groups (1.1 ppm).(H b) The chemical shift of the -CH- group move downfield ...

mass spectra - fragmentation patterns

chemguide.co.uk/analysis/masspec/fragment.html

The mass spectrum of pentane. Let's have another look at the mass spectrum for pentane: What causes the line at m/z = 57? How many carbon atoms are there in this ion? There can't be 5 because 5 x 12 = 60. What about 4? 4 x 12 = 48. That leaves 9 to make up a total of 57. How about C 4 H 9 + then?
